Spark Plug Gap With Electronic Ignition

Post by landisr »



My '76 LTD has an electronic ignition of unknown origin. Does anyone have thoughts or recommendations for a wider gap, considering it has the OEM coils?

I would suggest standard gap. If it works ok, stick with it.

"Spark Plug Gap Deviation:
Here is the combo i am currently running in my 75 engine.
DYNA-S,1.2 ohm resistor, no condenser, factory coils/wires/boots w/resistors, D7EA w/.035 plug gap on plan ol reg unleaded fuel.
Also here is a couple of great articles with more on the subject.

If you are running standard coils, the coils will never provide any greater spark than what they were with the original points fitted. The electronic part just replaces the points, so all it does is switch the coils on and off. Original gap will be perfect.

Thanks for the responses. I guess I will continue with stock specs.

Thanks again.
